This week, girl group Girls’ Generation completed the Taipei leg of their “Phantasia” tour. Member YoonA posted a group picture of all eight members on her Instagram account in commemoration of the event. In the picture, the girls show off their sisterly affection sporting warm smiles.

The joke that is referenced originates from Jo Se Ho’s appearance on MBC’s “Quiz to Change the World” last year. The comedian is asked why he had not gone to Ahn Jae Wook’s wedding by singer Kim Heung Gook in response to his comment that he takes care to remember special events of his celebrity colleagues. Jo Se Ho’s incredulous reaction, “Who is that? How can I go when I don’t know them,” and his deadpan facial expression became viral soon after, with netizens and celebrities alike joining in on playfully making fun of the comedian ever since.
